Q

talk about soil sampling?

A

the Radue’s get their soils sampled every year in a rotational system meaning each field will be tested once every three years. They select to test for nitrogen, phosphorus, potassium, organic matter & pH levels on their soil to plan for nutrient & fertiliser management.

Q

Cultivation & seedbed prep for Corn?

A

The land is ploughed using a chisel plough in Autumn to a depth of 6-8 inches after spreading slurry.

It is then left until Spring where we go in with a vertical disk to level out the land, this goes 2 inches deep.

Q

How is Corn sown?

A

Corn is sown using a corn sower at 30,000 seeds to the acre sown at a depth of 1.5-2 inches. When the weather is ideally 10 degrees Celsius. Once sown start up fertiliser is spread at a rate of 100 pounds per acre.

Q

Why/when is fungicide applied to corn?

A

Fungicide is applied in early August if there is signs of Northern Corn Leaf blight. They havent had issues for 3+ years so they dont apply unless required.

21
Q

When is corn silage harvested & how is it stored?

A

corn silage is harvested in Autumn. The entire plant minus the end 8 inches goes into the chopper & is chopped to about 3/4inches in length. A roller then compresses the corn kernels so it is available to the papillae in the stomach.

Stored in a pile at 62-70% moisture/

Q

How is high moisture corn harvested & stored?

A

harvested at 30& moisture. ground up very fine in a grinder before being stored in an ag bag.

25
Q

why is dry corn used?

A

It is used as a starch energy source in the cows diet. It also ups the butterfat production.

26
Q

What is the ideal dry corn moisture levels?

A

15% moisture when ground down

27
Q

How is dry corn harvested?
